As shown in FIG. 1, the communication system 1 includes a communication device 100a, a communication device 100b, a base station 200, a server 300a, a server 300b, and a server 300c. When it is not necessary to distinguish between the communication device 100a and the communication device 100b, they may be collectively referred to as the communication device 100. When it is not necessary to distinguish between the server 300a, the server 300b, and the server 300c, they may be collectively referred to as the server 300. In the communication system 1, the number of communication devices 100 is not particularly limited. In the communication system 1, the number of servers 300 is not particularly limited.

The communication device 100 is a wireless communication device that performs wireless communication with other devices. The communication device 100 performs wireless communication with, for example, the base station 200. The communication device 100 and the base station 200 are connected to each other so as to be able to communicate with each other via a public line network such as a telephone line network. The communication device 100 receives, for example, a communication speed limit start notification from the base station 200 when the upper limit of the predetermined communication amount is exceeded. The communication device 100 is, for example, a smartphone. The communication device 100 may be, for example, a mobile phone terminal, a tablet terminal, a wearable terminal, or the like.

The base station 200 is a communication device that performs wired communication or wireless communication between other devices. The base station 200 performs wireless communication with, for example, the communication device 100. For example, when the communication device 100 exceeds a predetermined upper limit of the communication amount, the base station 200 limits the communication speed of the communication device 100 and indicates that the communication speed is limited to the communication device 100. Sends the indicated communication speed limit start notification. The base station 200 is connected to the server 300 via a wired or wireless network N. The base station 200 communicates with the server 300 via the network N. Examples of the network N include, but are not limited to, the Internet network.

When the communication device 100 has information to be acquired from the server 300, the communication device 100 transmits an uplink signal including an information acquisition request to the base station 200. The base station 200 acquires information from the server 300 according to the information acquisition request.

In the example shown in FIG. 1, it is assumed that the communication device 100a is a communication device whose communication speed is limited, and the communication device 100b is a communication device whose communication speed is not limited. In this case, the uplink signal 11 transmitted by the communication device 100a to the base station 200 is slower than the uplink signal 13 transmitted by the communication device 100b to the base station 200. Similarly, the downlink signal 12 received by the communication device 100a from the base station 200 is slower than the downlink signal 14 received by the communication device 100b from the base station 200. In the present embodiment, when the communication speed of the uplink signal and the downlink signal becomes low, the process of preferentially acquiring the information desired by the user is performed. Here, the case where the communication speed of both the uplink signal and the downlink signal becomes low is described, but even when the communication speed of either the uplink signal or the downlink signal becomes low, the communication speed of either the uplink signal or the downlink signal becomes low. It may be configured to perform the process of preferentially acquiring the information desired by the user.

The communication device 100 transitions to the conditional information acquisition mode (step S11). The conditional information acquisition mode is a dedicated mode for acquiring priority information.

Upon receiving the HTTP request, the base station 200 switches to the priority information acquisition mode (step S12). The base station 200 transmits an HTTP request (for example, a URL (Uniform Resource Locator) including priority acquisition information) corresponding to the HTTP request received in step S10 to the server 300 (step S13). The server 300 transmits the HTTP response corresponding to the received HTTP request to the base station 200 (step S14). The base station 200 and the server 300 repeat the processes of step S13 and step S14 until all the priority information is received.

The base station 200 changes the transmission order in order to transmit the HTTP response received from the server 300 to the communication device 100 (step S15). The base station 200 transmits the priority information acquired from the server 300 to the communication device 100 as an HTTP response (step S16). The base station 200 repeats the process of step S16 until the transmission of all the priority information acquired from the server 300 is completed. In other words, the base station 200 repeats the transmission of the priority information a plurality of times according to the limited communication speed. When the transmission of the acquired data is completed, the base station 200 transmits an HTTP response indicating the end of transmission of all the priority information to the communication device 100 (step S17).

When the communication device 100 receives the HTTP response indicating the end of transmission of all the acquired data, the communication device 100 displays the priority information (step S18). When the communication device 100 displays the priority information, the communication device 100 switches from the conditional information acquisition mode to the normal mode (step S18).

The communication device 100 may disconnect from the base station 200 after transmitting the HTTP request in step S10. In this case, the base station 200 is. After acquiring the priority information from the server 300 and changing the transmission order, the base station 200 may perform a connection process to the communication device 100 to transmit the priority information.

[Overview of communication device processing]
An outline of the processing of the communication device according to the embodiment will be described with reference to FIG. FIG. 5 is a flowchart showing an outline of the processing flow of the communication device.

The control unit 170 determines whether or not the communication device 100 has a communication speed limit (step S100). Specifically, the detection unit 171 detects that there is a communication speed limit when the communication speed limit start notification is stored in the storage unit 160. If it is determined that there is a communication speed limit (step S100; Yes), the process proceeds to step S110. If it is determined that there is no communication speed limit (step S100; No), the process proceeds to step S140.

If it is determined to be Yes in step S100, the control unit 170 makes an information acquisition request including the communication speed limit information (step S110). Specifically, the request unit 172 makes an information acquisition request by transmitting an HTTP request including communication speed limit information to the base station 200.

The control unit 170 receives the reconstruction element information (step S120). Specifically, the generation unit 173 receives a plurality of reconstruction element information regarding information acquisition requests transmitted from the base station 200 in a predetermined order based on the communication speed limitation information via the reception unit 111. Then, the process proceeds to step S130.

The control unit 170 generates reconstruction information (step S130). Specifically, the generation unit 173 generates the reconstruction information based on the reconstruction information received in step S120. Then, the process of FIG. 5 is terminated.

If No is determined in step S100, the control unit 170 performs normal information acquisition processing (step S140). Specifically, the request unit 172 transmits the HTTP request to the base station 200 by a well-known method. In this case, the control unit 170 displays the information acquired by a well-known method. Then, the process of FIG. 5 is terminated.

[Details of communication device processing]
The details of the processing of the communication device according to the embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing details of the processing flow of the communication device according to the embodiment.

Since the process of step S200 is the same as the process of step S100 shown in FIG. 5, the description thereof will be omitted.

If it is determined to be Yes in step S200, the control unit 170 creates an HTTP request (step S210). Specifically, the request unit 172 describes the communication speed limit information and the priority acquisition information in the message body of the HTTP request. In other words, the request unit 172 adds an acquisition condition for acquiring information to the HTTP request. Then, the process proceeds to step S220.

FIG. 7 is a diagram for explaining priority acquisition information. The priority acquisition information is associated with the priority and the priority information. In the example shown in FIG. 7, the priority information having a priority of "1" is "P1", the priority information having a priority of "2" is "P2", and the priority information having a priority of "3" is "P1". It is shown to be "P3". In the example shown in FIG. 7, information is acquired in the order of "P1", "P2", and "P3". In the example shown in FIG. 7, the priority information is conceptually shown as "P1", "P2", "P3", etc., but in reality, for example, desired information is presented and a URL or the like is shown. ..

Return to FIG. The control unit 170 switches to the conditional information acquisition mode (step S220). Specifically, the communication control unit 174 switches to a dedicated mode for receiving priority acquisition information. Then, the process proceeds to step S230.

The control unit 170 sets a timeout (step S230). Specifically, the execution unit 175 sets a waiting time until a timeout occurs after the HTTP request is transmitted. Then, the process proceeds to step S240.

The control unit 170 transmits an HTTP request (step S240). Specifically, the request unit 172 makes an information acquisition request by transmitting the HTTP request created in step S210 to the base station 200 via the transmission unit 112. Then, the process proceeds to step S250.

The control unit 170 determines whether or not a time-out has occurred (step S250). Specifically, the execution unit 175 determines whether or not the timeout time set in step S230 has elapsed after transmitting the HTTP request. If it is determined that the time-out has not occurred (step S250; No), the process proceeds to step S260. If it is determined that the time-out has occurred, the process proceeds to step S310.

If No is determined in step S250, the control unit 170 receives the HTTP response (step S260). Specifically, the generation unit 173 receives the HTTP response transmitted from the base station 200 in response to the HTTP request. Then, the process proceeds to step S270.

The control unit 170 displays the received information (step S270). Specifically, the execution unit 175 generates reconstruction information regarding the priority acquisition information generated by the generation unit 173 based on the HTTP response, and causes the display unit 140 to display the reconstruction information. Then, the process proceeds to step S280.

The control unit 170 determines whether or not the priority acquisition end information indicating that the transmission of the priority information has been completed has been received (step S280). If it is determined that the priority acquisition end information has been received (step S280; Yes), the process proceeds to step S290. When it is determined that the priority acquisition end information has not been received (proceed to step S250). That is, the control unit 170 repeatedly executes the processes of steps S250 to S280 until the time-out occurs or the priority acquisition end information is received.

If it is determined to be Yes in step S280, the control unit 170 switches to the normal mode (step S290). Specifically, the communication control unit 174 switches to a normal mode in which normal communication is performed. Then, the process of FIG. 6 is terminated.

Since the process of step S300 is the same as the process of step S140 shown in FIG. 5, the description thereof will be omitted.

If it is determined to be Yes in step S250, the control unit 170 displays the failure of information acquisition (step S310). Specifically, the execution unit 175 causes the display unit 140 to display a display indicating that the acquisition of the priority information has failed. The execution unit 176 causes the display unit 140 to display, for example, a character such as "Failed to acquire priority information." Then, the process proceeds to step S290. That is, when a timeout occurs, the control unit 170 ends the priority information acquisition process.

In the process shown in FIG. 6, when a time-out occurs, the priority information acquisition process is terminated, but the process of the present embodiment is not limited to this. For example, when a timeout occurs, the control unit 170 may perform the priority information reacquisition process without ending the priority information acquisition process. In addition, here, the acquisition process is completed up to the point where the acquisition was possible, the reconstruction information related to the priority acquisition information is generated, and when the reconstruction information is displayed, the reception fails at the location that could not be acquired. May be configured to display.

Further, when the communication device 100 receives the communication speed limit start notification from the base station 200, the execution unit 175 does not have to store the communication speed limit start notification in the storage unit 160. In this case, the communication device 100 executes a normal information acquisition process for the base station 200, and when the base station 200 notifies that the communication speed is limited, steps S210 to FIG. 6 are shown. The process of step S290 may be executed.

Further, in FIG. 6, it is configured to return to the normal acquisition mode after the information acquisition in the priority information acquisition mode is completed, but it returns to the normal acquisition mode based on the return condition for returning to the normal acquisition mode. It may be configured to determine whether or not. For example, as a return condition, the communication device 100 may be configured to store the date and time when the speed limit notification is received and to continue the priority information acquisition mode for a predetermined period. Further, the return condition may be configured so that the user operates the communication device 100 and manually sets the return condition. For example, if the user recognizes that the communication speed is limited and purchases a new communication capacity, the recovery condition may be set manually and the device may be configured to return to the normal acquisition mode. good.

The processing of the base station according to the embodiment will be described with reference to FIG. FIG. 8 is a flowchart showing an example of the processing flow of the base station.

The base station 200 receives an HTTP request from the communication device 100 (step S400). The base station 200 determines whether or not the received HTTP request is conditional on acquisition (step S410). If it is determined that the acquisition condition is conditional (step S410; Yes), the process proceeds to step S420. If it is determined that the acquisition information is not attached (step S410; No), the process proceeds to step S500.

If it is determined to be Yes in step S410, the base station 200 stores the priority acquisition information included in the HTTP request (step S420). The base station 200 transmits an HTTP request to the server 300 (step S430). The base station 200 receives the HTTP response to the HTTP request from the server 300 (step S440).

The base station 200 determines whether or not all the priority information desired by the user has been acquired from the server 300 (step S450). If it is determined that all the priority information has been acquired (step S450; Yes), the process proceeds to step S460. If it is determined that all the priority information has not been acquired (step S450; No), the process proceeds to step S430. That is, the base station 200 repeats the processes of steps S430 to S450 until all the information desired by the user is acquired.

If it is determined to be Yes in step S450, the base station 200 changes the transmission order based on the priority acquisition information stored in step S420 (step S460). Specifically, the base station 200 changes the transmission order so that the priority information having a higher priority is transmitted first.

The base station 200 transmits an HTTP response including the acquired priority information to the communication device 100 (step S470). The base station 200 determines whether or not the transmission of all priority information has been completed (step S480). When it is determined that the transmission of all the priority information is completed (step S480; Yes), the process proceeds to step S490. If it is determined that the transmission of all priority information has not been completed (step S480; No), the process proceeds to step S470. That is, the base station 200 repeats the processes of step S470 and step S480 until the transmission of the designated information to the communication device 100 is completed.

If it is determined to be Yes in step S480, the base station 200 transmits an HTTP response including priority acquisition end information to the communication device 100 (step S490). Then, the process of FIG. 8 is terminated.

If No is determined in step S410, the base station 200 executes a normal information acquisition process for the server 300 (step S500). Then, the process of FIG. 8 is terminated.

If the capacity of the information to be transmitted to the communication device 100 is large in step S470, the base station 200 may compress or process the information and then transmit the information to the communication device 100.

Further, in step S460, the base station 200 does not have to change the transmission order when "the upper limit of the amount of information in the communication speed limit ≥ the amount of information acquired from the server 300".

Further, in step S490, when the base station 200 has information other than the designated information, the base station 200 does not transmit the priority acquisition end information but transmits the information other than the designated information to the communication device 100. You may.

As described above, in the present embodiment, when the communication speed is limited, the information acquisition request is made including the information indicating that the communication speed is limited and the information desired to be acquired. Thereby, in the present embodiment, even when the communication speed is limited, the information desired by the user can be preferentially acquired and displayed.

Further, in the present embodiment, the communication between the communication device 100 and the base station 200 can be stopped when the user obtains the desired information, so that the increase in the communication amount can be suppressed and the remaining battery level can be reduced. It can be suppressed.
